You could really go with any one of those lighting types and get great results. The biggest difference is going to be start up cost and maintenance cost. T5 will be the cheapest to start up with followed by halide then LED. Maintenance cost will be cheapest for LED then t5 and lastly halide. Lighting is an investment that will effect the outcome of your tank over the long term, so be sure to research a lot before you buy. Is there a price range you were looking at?

alright. so im unsure on the 90 now... i have found some amazing deals on craigslist that are complete setups with live rock and such for around $1000. one of the tanks ill be looking at was a build here on 3reef. so itll be exciting to see. ive found some others that im also considering that also include metal halides and good protein skimmers. each of these are 90 gals or more. what do you guys think i should do?

Get the complete setups on craigslist or on here. My first tank was not that great of a deal, my second was okay. Now that I know craigslist, forums, ebay and other reefer friends the deals cannot be beat. If you can get a complete setup for under 1k get it. If you wait a little longer closer to Christmas you may get better deals.
